How to Store Prescription Medications Properly

## Why storage matters Proper medication storage is essential for maintaining drug effectiveness and safety. Medications stored incorrectly can lose potency, degrade into harmful compounds, or become contaminated. Studies show that up to 35% of households store medications in the bathroom medicine cabinet — one of the worst locations due to heat and humidity from showers. ## General storage guidelines Most oral medications should be stored at controlled room temperature, between 68°F and 77°F (20°C and 25°C), with brief excursions permitted up to 86°F (30°C). Keep medications in a cool, dry place away from direct sunlight. A bedroom dresser drawer or a kitchen cabinet away from the stove are good options. Always keep medications in their original containers with the lids tightly closed. The original containers are designed to protect against moisture and light. Childproof caps should remain on if children are present in the home. ## Medications requiring refrigeration Some medications must be refrigerated between 36°F and 46°F (2°C and 8°C). Common refrigerated medications include insulin, certain eye drops, some liquid antibiotics, and some injectable medications like GLP-1 receptor agonists (semaglutide, liraglutide). Do not freeze these medications unless the label specifically states they can be frozen. When traveling with refrigerated medications, use an insulated bag with ice packs. Never place medications directly against ice or in the freezer compartment. ## Special storage requirements Nitroglycerin tablets must be stored in their original glass container and replaced every 6 months after opening. Light and air exposure rapidly degrade nitroglycerin. Inhalers should be stored at room temperature. Some inhalers should not be punctured or used near heat or open flames due to the propellant. Suppositories may need refrigeration to maintain their shape, depending on the formulation. Check the label. ## Signs of degraded medications Discard medications that show signs of degradation: changes in color, odor, or texture; tablets that are crumbling, chipping, or sticky; cloudy or discolored liquids; or medications past their expiration date. When in doubt, ask your pharmacist.
